The pickup unit 5 enters the space formed by the division, and takes out the CD4 from the stocker 13 to reproduce it, or returns the reproduced CD4 to the stocker 13 . The actions of each part are controlled by the control circuit 19 .

The stocker 13 and the stand 16 are supported by a chassis 20 . The chassis 20 is supported by the floating mechanism 17 so as to float relative to the casing 12 .

If a plurality of recording media are loaded together into the device in a cassette type, the positioning accuracy can be maintained while the recording media are placed in the cassette. However, the recording media cannot be inserted or removed individually, and the entire case must be taken out of the device, making it troublesome to replace the recording media.

75 and 76A to 76E of the CD playback device 1 of the previous application, in order to automatically perform all operations, it is necessary to use an optical sensor for precise positioning of the CD 4 . But, in the interior of limited casing 12, CD4 is conveyed, especially the action that CD4 is conveyed to the narrow storage position of stocker 13 with conveying roller 16a, if the structure of conveying roller 16a is simplified and adjusted, it will be very difficult. difficulty. Then, the inserted CD 4 is put into the stocker 13, and is positioned as a reference position for insertion and removal between the transport rollers 16a and transfer with the pickup unit 5 for reproduction. Therefore, it is actually necessary to have a lever for pushing the CD4 into the stocker 13 reliably, and a lever for pushing the CD4 stored in the stocker 13 to the position of the conveying roller 16A, etc., which complicates the structure.

As for the groove, the locking shaft can be easily inserted at the beginning before the locking member moves. By moving the lock member, the lock shaft inserted into the beginning of the groove can be guided to the end where the width of the groove is substantially equal to the outer diameter of the lock shaft, thereby restricting the movement of the lock member. The terminal end of the second locking portion in the moving direction is coupled with the coupling member to restrict a direction perpendicular to the moving direction. In this way, relative to the casing, the supporting substrate is respectively restricted in the same direction as the moving direction or in a direction perpendicular to the moving direction, so that the floating state is eliminated.

The locking portion restricts the same direction as the moving direction of the supporting substrate, and is coupled with the coupling portion of the coupling member at the end of the moving direction to restrict the direction perpendicular to the moving direction. Therefore, by combining the movement of the member, the same direction as the movement direction and the direction perpendicular to it can be restricted at the same time.

Another feature of the present invention is that: the above-mentioned connecting member is provided with a gap from the above-mentioned supporting substrate to form a connecting portion,

According to the present invention, the pinning groove set up on the side of the locking mechanism away from the support substrate, together with the first locking portion of the locking member, also uses the locking lever to limit the displacement, so the parallel The displacement in the plane of the moving direction is effectively limited. The second locking portion of the locking member is engaged with the coupling portion formed at a certain distance from the support substrate, so that the support substrate can be restrained at a high-precision position relative to the housing.

Another feature of the present invention is that the lock mechanism is interlocked with the division of the storage mechanism, and restricts the floating state when the recording medium is being reproduced and/or recorded.

FIG. 1 shows a schematic overall structure of a CD reproducing apparatus 21 having a vehicle-mounted automatic disc changer function according to an embodiment of the present invention. The casing 22 is used as a vehicle-mounted device, and its size conforms to the standard IDIN, namely about 18 cm in width, 5 cm in thickness, and 17 cm in depth. The casing 22 is installed on an instrument panel or the like of a vehicle, and its thickness direction constitutes a substantially vertical direction.

A stocker 23 serving as a storage mechanism is arranged inside the cabinet 22, and can store six disc-shaped recording media CD24. The CD 24 has a diameter of about 12 cm and a thickness of about 1.2 mm, and can be reproduced by the pickup unit 25 of the reproducing mechanism. The stocker 23 can be moved up and down as a whole by the lifting mechanism 26 as a selection mechanism. The floating mechanism 27 only makes the pickup unit 25 float, and is mechanically lifted from other parts, and can prevent the influence of external vibration and impact when the CD 24 is mounted on the pickup unit 25 for reproduction. If utilize elevating mechanism 26 to select a storage position, then storage container 23 is divided into upper and lower two parts by dividing mechanism 28, can make to reserve space between the divided storage positions. An electronic circuit board and the like constituting a control circuit 29 are arranged on the side of the casing 22 to control the movement of each part.

The pickup unit 25 can be displaced on the sliding seat 30 supported from the bottom of the casing 22, and the sliding seat 30 can be maintained in a floating state by the floating mechanism 27, and is mechanically lifted from the bottom of the casing 22. The control circuit 29 uses the locking mechanism 31 to eliminate the floating state formed by the floating mechanism 27 except when CD24 is regenerated. The pickup unit 25 is independent of other parts in the casing 22 and does not float.

An insertion/extraction port 33 is formed on a front panel 32 serving as an operation surface of the cabinet 22 for inserting or removing the CD 24 . An insertion and removal mechanism 34 is provided beside the insertion and removal opening 33 in the housing 22 . The insertion and removal mechanism 34 includes an insertion and removal roller 35 and a support plate 36 . The CD 24 inserted or removed from the insertion/extraction port 33 is placed on the support plate 36 , and is conveyed in the insertion direction or the extraction direction by the rotation of the insertion/extraction roller 35 . When transferring or reproducing the CD 24 in the cabinet 22, the insertion and removal port 33 is closed by a shutter mechanism 37 constituting a switch mechanism. Then, the CD 24 inserted into the case 22 is transported to the opposite direction of taking out, and brought into contact with the shutter mechanism 37 for positioning. In the illustrated state, the turntable 38 of the pickup unit 25 is on standby at the reference position, and if the CD 24 inserted from the insertion/extraction port 33 is positioned, it can be received. The stocker 23 is formed by stacking disc bases 39 that can store CDs 24 separately. On the turntable 38, a chucking mechanism 40 for storing the CD 24 is provided.

When the CD 24 is inserted into the casing 22, the shutter mechanism 37 in FIG. 1 closes the insertion and removal opening 33, and a new CD 24 cannot be inserted. Once the insertion and removal roller 35 has introduced the CD 24 into the casing 22, it rotates in the opposite direction and pushes the CD 24 back until it is stopped by the shutter 37. In this way, the CD24 can be accurately placed at a certain position, even if it is located near the insertion and removal opening 33 inside.

Fig. 3 shows that to the CD24 that has been positioned, the pick-up unit 25 that stands by below rises, and CD24 is clamped and put on the turntable 38, and it is moved to the state in the compartment 23 that has been divided. In addition, the inserted CD 24 may be reproduced in its original state by using the pickup unit 25 .

FIG. 4 shows a state in which the CD 24 placed on the turntable 38 is transferred from the pickup unit 25 moved into the space in the stocker 23 to the disc base 39 constituting the stocker 23. Disc base 39 waits below the CD24 that is put on the turntable 38 and carries out transmission, then rises, and the peripheral edge of holding CD24 is lifted upwards, and CD24 is taken off from turntable 38. And, when the CD24 stored in the stocker 23 is transferred to the turntable 38 of the pickup unit 25 to be taken out, the disc base 39 descends, and the stored CD24 is transferred to the turntable 38 . When storing in the storage unit 23, the pickup unit 25 to which the CD24 has been transferred to the disc base 39 is taken out from the space between the storage units 23. When taking out the CD24, the pickup unit 25 on which the CD24 obtained from the disc base 39 in the storage container 23 is installed is pulled out, and the CD24 is transferred to the insertion and removal mechanism 34.

5A, 5B, and 5C are plan views showing schematic operating states of the CD playback device 21. As shown in FIG. In the cabinet 22 of the CD playback device 21, a plurality of CDs 24 can be stored in the drawer 23. In the stocker 23, CD24 is stacked and stored in the thickness direction, and can be divided up and down in the thickness direction at an arbitrary position. The arc-shaped movement carried out by the rotating rod 27 and the linear movement carried out by the moving mechanism 28 are combined by the player of the playback device of the recording medium, so that the turntable 26 of the pickup unit 25 can enter and exit in the space formed after the division. .

FIG. 5A shows a state in which the turntable 26 has withdrawn from the movement range of the CD 24 stored in the stocker 23 . FIG. 5B shows a state where the rotary arm 27 is rotated and displaced, and the turntable 26 is on standby at a position on the center line 24a through which the center of the CD 24 inserted from the outside of the cabinet 22 passes. FIG. 5C shows a state in which the CD 24 is supported by the turntable 26 and the CD 24 is conveyed into the space formed by the division in the stocker 23 . Movement between the various states of FIGS. 5A , 5B and 5C is controlled by a control circuit 29 disposed on one side of the housing 22 .

Figures 6A to 6H, Figures 7A to 7F, Figures 8A to 8F, Figures 9A to 9I, and Figures 10A to 10L respectively show the insertion, removal, storage, regeneration and replacement of CD24 in the CD playback device 21 of this embodiment. summary of the action. Fig. 6A shows an insertion ready state. The insertion/extraction mechanism 34 is in the state which can lower the insertion/extraction roller 35, and can draw in the inserted CD24. In the stocker 23, for the disk base 39 corresponding to the selected storage position, all the disk bases on the lower side of the disk base are lowered, leaving a gap, and all the disk bases on the upper side of the selected disk base 39 are raised. . CD24 is stored in the space between the selected disc base 39 and the disc base above it. The pickup unit 25 is on standby at a standby position on the exit side of the insertion/extraction mechanism 34 .

FIG. 6B shows a state where the user of the CD playback device 21 has inserted one CD 24 through the insertion and removal opening 33 in FIG. 1 . The insertion and removal roller 35 of the insertion and removal mechanism 34 temporarily introduces the inserted CD 24 into the casing 22 as shown in FIG. 6C, and conveys it in the reverse direction as shown in FIG. 6D for positioning. As shown in FIG. 6C, after the CD 24 is introduced, the shutter mechanism 37 of FIG. 1 is closed. As shown in FIG. 6D , if the CD 24 is conveyed in the reverse direction, the rear end of the CD 24 can come into contact with the shutter mechanism 37 in FIG. 1 and stop for positioning.

For the CD24 that has been positioned among Fig. 6D, in Fig. 6E, pick-up unit 25 rises, and CD24 is put on the turntable 38, obtains CD24, and clamping mechanism 40 is set on turntable 38, as shown in Fig. 6F, makes the card Tight mechanism 40 actions, CD24 is fixed on the turntable 38. Then, the pickup unit 25 is moved to the insertion direction, and the CD24 is pulled out from the insertion and removal mechanism 34, as shown in Figure 6G, the CD24 is moved in the storage device 23, and the CD24 is released in the PLAY state shown in Figure 6H. 1, the pickup unit 25 forms a mechanically floating state by means of the floating mechanism 27 of FIG. 1, and reproduces the information of the CD24.

7A to 7F show the process of taking out the CD 24 from the playback state shown in FIG. 6H. In the regeneration state of FIG. 7A , the lock mechanism 31 of FIG. 1 cancels the locked state, but in FIG. 7B , the lock mechanism 31 of FIG. 1 is activated to stop the floating state generated by the floating mechanism 27 of FIG. 1 . In FIG. 7C , the pickup unit 25 is moved from the inside of the storage 23 to the standby position on the outlet side of the insertion/extraction mechanism 34 . In FIG. 7D , the clamping mechanism 40 is operated to cancel the fixed state of the CD 24 on the turntable 38 . 7E, the pickup unit 25 descends on the standby position, and the insertion and removal roller 35 of the insertion and removal mechanism 34 also descends, so that the CD24 remains between the insertion and removal roller 35 and the support plate 36. In this way, the CD 24 is transferred from the pickup unit 25 to the insertion/extraction mechanism 34 side. In Fig. 7F, the CD 24 is taken out by inserting and rotating the opening 35. The taking out operation stops temporarily while the CD 24 is protruding from the insertion and removal port 33 in FIG. 1 , and waits for the user of the CD playback device 21 to take out the CD 24 .

8A to 8F show the outline of the storing operation for storing the CD 24 in the storing position in the stocker 23 . However, the PLAY state shown in FIG. 6H will be described as the PLAY state shown in FIG. 8A. When storing the CD 24 inserted through the insertion/extraction port 33 into the storage unit 23, after the operation from FIG. 6A to FIG. 6H, the CD 24 is stored immediately without reproduction. In FIG. 8B , the locking mechanism 31 of FIG. 1 is operated, and after the floating state is canceled, the pickup unit 25 and the disc base 39 for storing the CD 24 are raised. In FIG. 8C, the state in which the CD 24 is fixed to the turntable 38 by the chucking mechanism 40 of the pickup unit 25 is eliminated. In FIG. 8D , the pickup unit 25 moves downward, and the CD 24 is transferred from the turntable 38 to the disk base 39 . In FIG. 8E , the pickup unit 25 moves to a position below the insertion and removal mechanism 34 , and in FIG. 8F , all the divided storage containers 23 descend, and the divided state is eliminated.

9A to 9I show the operation process in which an arbitrary CD 24 stored in the stocker 23 is taken out. As shown in Figure 9A, the pickup unit 25 is positioned at the below of the insertion and removal mechanism 34, and from the state where the storage device 23 has all been lowered, if the disk seat 39 that stores the CD24 that should be taken out is selected, then as shown in Figure 9B , the stocker 23 is divided to form an upper part (including the selected disk base 39 ) and a lower part (below the selected disk base 39 ). In FIG. 9C , the pickup unit 25 moves into the space in the container 23 formed after division. In FIG. 9D , the pickup unit 25 rises, and the CD 24 taken out is placed on the turntable 38 . In FIG. 9D , the clamp mechanism 40 of the turntable 38 is operated to clamp (fix) the CD 24 . In FIG. 9E , the disc base 39 in which the CD 24 has been placed is lowered, and the CD 24 is moved toward the turntable 38 side. In FIG. 9F , the pickup unit 25 including the turntable 38 on which the CD 24 is loaded moves from the space formed between the storage boxes 23 to the standby position on the exit side of the insertion and removal mechanism 34 . The CD 24 is inserted into the support plate 36 where the insertion/extraction roller 35 is pulled upward. In Fig. 9G, the state that CD24 is clamped and fixed on the turntable 38 by the clamping mechanism 40 is eliminated; Between the support plate 36, the CD 24 is removed from the turntable 38, the insertion and removal roller 35 is rotated, and the CD 24 is taken out. In FIG. 9H, if the CD24 is removed from the insertion and removal port 33 by the user, the machine becomes a waiting state where the CD24 can be reinserted.

10A to 10L show the transition from the PLAY state in which one CD 24 is being reproduced to another CD 24 stored in the stocker 23. The operations from FIG. 10A to FIG. 10F are the same as those in FIGS. 8A to 8F . The operations from FIG. 10G to FIG. 10K are the same as those in FIGS. 9A to 9E . In Fig. 10L, unclamp the locking mechanism 31 of Fig. 1, after the pick-up unit 25 becomes the floating state on the machine by means of the floating mechanism 27 of Fig. Regeneration of CD24. Because the locking action performed by the locking mechanism 39 of FIG. 1 is released, the CD24 can be reproduced in a state where the impact and vibration from the outside are difficult to be transmitted to the pickup unit 25 by the floating mechanism 27. But, owing to absorb vibration, may produce relative displacement between pick-up unit 25 and other parts, so the pick-up unit 25 that CD24 has been housed is preferably moved to the position that CD24 can not bump into surroundings.

FIG. 11 shows the appearance of the CD playback device 21 of FIG. 1 . Selection buttons 41 to 46 are provided around the insertion/extraction opening 33 of the front panel 32 , and the storage position of the CD 24 stored in the storage box 23 can be designated. In the storage position, for example, numbers 1 to 6 are compiled from bottom to top, and the corresponding numbers are designated with the selection buttons 41 to 46 .

FIG. 12 shows the structure of the mechanical part of the CD playback device 21 in FIG. 1 with the cabinet 22 removed. Fig. 13 and Fig. 14 show the states of the mechanism shown in Fig. 12 viewed from the front and viewed from the back, respectively. Fig. 15, Fig. 16 and Fig. 17 respectively show the front state, the right cross-sectional state, and the left side state when the CD 24 is inserted. The front panel 32 side of the removed cabinet 22 is defined as the front side, and the side opposite to the front panel 32 is defined as the rear side, and the entire mechanism is supported by the chassis 50 . On the chassis 50 , the shutter mechanism 37 , the insertion/extraction mechanism 34 and the like are arranged on the front side, and the stocker 23 and the like are arranged on the rear side.

The pickup unit 25 can move forward and backward so that the center position of the turntable 38 is on the centerline 51 of the chassis 50 between the reference position for standby shown in FIG. Furthermore, from the reference position shown in FIG. 15 , the turntable 38 may be rotated and displaced from the reference position shown in FIG.

The elevating mechanism 26 that makes the storage container 23 move up and down, the dividing mechanism 28 that separates the storage container 23, and the mechanism that makes the pickup unit 25 and the locking mechanism 31 act are all used as various slides that move back and forth in the front-back direction. Plates and the like are arranged on both sides in the width direction of the chassis 50 . In order to drive the slide plate, a lifting motor 52 and a dividing motor 53 are respectively arranged at rear corner portions of the chassis 50 .

The lift motor 52 moves the lift slide plate 54 in the front-rear direction of the tray bottom 50 , and selects the storage position of the stocker 23 based on the number of stages calculated by the counter sensor 55 . The stocker 23 is divided by the division slide plate 56 driven by the division motor 53 at the storage position selected by the lift motor 52 .

A split origin switch 57 and a lift origin switch 58 indicating the origin positions of the split slide plate 56 and the lift slide plate 54 are respectively provided on the front side and the rear side of the chassis 50 . The intermediate position of the slide plate 56 for division is detected by the division position detector 59 . The division position detector 59 is a variable resistor that changes linearly, and its use method is to represent the position with an analog voltage. The detection output is A/D converted and processed as a digital value.

In this embodiment, the insertion/extraction roller 35 is also driven by the elevating motor 52 . The insertion and removal roller 35 descends only when inserting or taking out the CD 24, and rises in other states. Therefore, in order to simplify the mechanism, the insertion and removal roller 35 is usually driven by the elevating motor 52. The connected state is: when the container 23 needs to be moved up and down, the clutch mechanism is activated to transmit the driving force to the sliding plate 54 for lifting. In the clutch mechanism of the present embodiment, its connected state is: when the sliding plate 56 is positioned at the most retreated position for division, the driving force from the lifting motor 52 can be transmitted to the sliding plate 54 for lifting. When the sliding plate 56 for division is separated from the rearmost position, the clutch mechanism 58 is disconnected so that the driving force from the motor 52 cannot be transmitted to the sliding plate 54 for raising and lowering.

FIG. 18 shows the structure of the slide unit 60 formed on the slide base 30 in order to move the pickup unit 25 . FIG. 19 shows a state in which the slide plate 61 of the slide unit 60 is moved rearward with respect to the slide base 30 as viewed from the front. FIG. 20 shows the structure related to the rotating plate 62. As shown in FIG. The sliding unit 60 generally has a sliding plate 61 and a rotating plate 62 . The slide plate 61 is movable in the front-rear direction relative to the slide base 30 . The rotating plate 62 can rotate and displace around the rotating shaft 63 provided on the base end side, so that the pickup unit 25 on the distal end side draws an arc with respect to the sliding plate 61 . An arc-shaped guide groove 64 for guiding when the rotary plate 64 is rotationally displaced is formed on the rotary plate 61 . An L-shaped guide groove 65 is formed on the slide base 30 and has a vertical groove 66 and a horizontal groove 67 . A projection 68 combined with the L-shaped guide groove 65 of the sliding seat 30 is provided on the rotating shaft 63. During the combination of the projection 68 and the transverse groove 67 of the L-shaped guide groove 65, the projection provided on the rotating plate 62 69 is combined with the arc-shaped guide groove 64 of the sliding plate 61, and the rotating plate 62 is rotated and displaced. When the protrusion 68 of the shaking plate 62 is combined with the longitudinal groove 66 side of the L-shaped guide groove 65, the rotating plate 62 can no longer be rotated and displaced, and can only move forward and backward in the state where the longitudinal groove 66 and the protrusion 68 are combined. of the mobile.

The movement of the pickup unit 25 on the rotary plate 62 is realized by the feed motor 70 rotating the feed screw shaft 71 . The pickup unit 25 is located at the origin position on the turntable 38 side, which is detected by the PU origin switch 72 . In a general pickup unit, when the pickup unit reaches the original position, the feed motor 70 is no longer driven. In this embodiment, the clamping state by the clamping mechanism 40 can also be eliminated by further driving the feed motor 70 without mechanically stopping the pickup unit 25 at the origin position. The release of the jammed state is detected by the jam release switch 73 . The turntable 38 is directly rotationally driven by a spindle motor 74 .

The relative movement between the sliding unit 60 and the sliding seat 30 is driven by the sliding motor 75 . The slide motor 75 is provided on the carriage 30, and the moving position of the slide plate 61 is detected by a slide origin switch 76, a slide end switch 77, and an insertion/extraction standby switch 78, respectively. In the slide unit 60, in the gear mechanism for transmitting the driving force from the slide motor 75 to the slide plate 61, a slide mechanism 79 is provided for preventing transmission of excessive driving force. The forward movement of the slide plate 61 is stopped when the pin 61 a comes into contact with a predetermined insertion/extraction mechanism 34 .

The floating shaft 60a, the locking shaft 60b, and the locking piece 60c protrude toward the back side of the slide base 30. As shown in FIG. The floating shaft 60a is used to make the sliding unit 60 appear in a floating state. The locking shaft 60b and the locking plate 60c are used to eliminate the floating state.

FIG. 21 shows the structure of the slide mechanism 79 . In the slide mechanism 79, two gears 79b and 79c are provided on a common shaft 79a. The gear 79b connected to the slide motor 75 is fixed to the shaft 79a. The gear 79c connected to the side of the slide plate 61 is not fixed to the shaft 79a, but is rotatable around the shaft 79a. Since the gear 79c is pressed against the retaining ring 79d fixed on the shaft 79a by the spring 79e, the driving force is transmitted by the frictional force between the gear 79c and the retaining ring 79d.

When the driving force exceeds the frictional force, the driving force transmitted from the gear 79d to the shaft 79a cannot be transmitted from the stop ring 79d to the gear 79b, resulting in idling. In this way, if the sliding plate 61 is stretched out the most relative to the sliding seat 30, the pickup unit 25 is entered into the storage container 23, or the sliding plate 61 is pulled back the most relative to the sliding seat 30, because Mechanical block and be in stop state, so, slide mechanism 79 just carries out idling. If the control is performed such that the slide motor 75 is driven for a sufficient time before the slide mechanism 79 idles and then the slide motor 75 is stopped, then the stop position of the slide plate 61 can be precisely determined.

In the control method that uses a photodetector or the like to detect the position and stop it, it is difficult to accurately determine the position due to the influence of mechanical control delay and the like. In this embodiment, a simple control method can be used to accurately perform high-precision positioning.

The linear movement of the sliding unit 60 is to transmit the driving force from the sliding mechanism 79 to both sides of the sliding seat 30 by the linkage shaft, and is carried out by the gear mechanism of the same structure. Since both sides are driven simultaneously and in a balanced manner, smooth movement is possible.

FIG. 22 shows the structure of the switch mechanism including the insertion/extraction mechanism 34 and the shutter mechanism 37. As shown in FIG. Driving forces from the lift motor 52 and the split motor 53 arranged at the rear are transmitted to the spur gears 80, 81, respectively. Because the insertion and removal roller 35 of the insertion and removal mechanism 34 is driven by the elevating motor 52 arranged at the rear as described above, the drive shaft 82 for driving the spur gear 80 is installed on the base end to extend the installation, and its front end is aligned with the gear. Mechanism 83 is connected. The driving force from the split motor 53 at the rear is also transmitted by the drive shaft 84 on which the spur gear 81 is installed at the base end. The provided gear mechanisms 86 and 87 equally drive the dividing slide plate 56 in the front-rear direction.

The shutter mechanism 37 of the switch mechanism includes a sliding plate 88 a for switching, a sliding member 88 b for a shutter, and a shutter member 88 c. The switch mechanism also includes a switch pin 89a, and a switch stopper 89b and a slide plate 89c for the pin are provided in relation to the switch pin 89a. The switch pins 89a are respectively arranged on both sides in the lateral direction to form a pair, and the interval thereof is smaller than the diameter of the CD24 to prevent repeated insertion of the CD24. When the CD 24 is first inserted and removed, the switch pin 89a avoids the movement range of the CD 24 by the pressure contacting the CD 24 so as not to interfere with the movement of the CD 24 . The switch pin 89a is prevented from being displaced by the switch stopper 89b when preventing repeated insertion, even if it overlaps with the CD24, it does not avoid it, preventing the CD24 from moving. As mentioned above, the shutter member 88c is used to reversely rotate the insertion/extraction roller 35 to position the inserted CD 24 .

In addition, in association with insertion and removal of CD24, insertion detection switch 90a, insertion presence/absence switch 90b, insertion end switch 90c, and removal end switch 90d are also provided.

FIG. 23 shows an outline of a gear mechanism employed for driving the sliding plate 56 for division and the insertion/extraction roller 35 . A bevel gear 83a constituting a gear mechanism 83 is provided at the front end of the drive shaft 82, and the driving force from the lift motor 52 through the spur gear 80 is transmitted to the bevel gear 83a and the spur gear 83c. A bevel gear 84a is provided at the front end of the drive shaft 84, and the driving force from the split motor 54 via the spur gear 81 is transmitted to the bevel gear 84b and the spur gear 84c. On the connecting shaft 85, spur gears 85a and 85b are provided on the right end side, and a spur gear 85c is provided on the left end side. The driving force from the split motor 54 is transmitted to the spur gear 85a through the spur gear 86b inserted into the shaft 86a of the gear mechanism 86 .

The spur gear 86b is not fixed to the shaft 86a, but can freely rotate around the shaft 86a. On both ends of the shaft 86a of the gear mechanism 86, a spur gear 86c and a pinion gear 86d are provided. The gear mechanism 87 on the left end side has a spur gear 87b rotatable around the shaft 87a, spur gears 87c and pinion gears 87d provided on both ends of the shaft 87a, and has the same structure as the gear mechanism 86 on the left end side.

When the driving force is transmitted to the spur gear 85a, the connecting shaft 85 rotates, and the driving force is transmitted to the spur gears 86c, 87c through the spur gears 85b, 85c, respectively.

This driving force rotates the pinion gears 86d, 87d, and drives the racks of the sliding plates 56b, 56a for division in the front-rear direction. Furthermore, in the gear mechanism 87 on the left end side, the driving force from the lift motor 52 transmitted through the drive shaft 82 is transmitted to the drive mechanism of the insertion/extraction roller 35 through the spur gear 87b.

That is, the gear mechanism 83 also includes spur gears 83d and 83e driven from the spur gear 83c via the spur gear 87b of the gear mechanism 87 . The spur gear 83e is attached to the insertion/extraction roller 35, and can drive the insertion/extraction roller 35 to rotate. When the lift motor 52 is rotated, the insertion/extraction roller 35 is normally rotationally driven. However, as will be described later, if the insertion/extraction roller 35 is located at the raised position shown in FIG. 39A, it will not have any effect even if it is rotated.

The dividing protrusions 93 to 96 of the disc base 39 at the divided storage position rise along the slope of the upper cam portion 120 . Based on the divided disc base 39 , the lower disc base is controlled to ascend by the lower side cam portion 121 . The division protrusions 93 to 96 that rise up on the slope along the upper cam portion 120 are separated by the separation portion 122 into the disk base 39 at the storage position and the disk base 39 above it. When the uppermost disc base 39 is selected, the division protrusions 106 to 109 of the top plate 104 are separated by the separation part 122 . The disc seat 39 on the lower side is further compressed by the pressing portion 123 by elastic action. Movement of the sliding plate 56 for division in the front-rear direction is realized by driving the rack 124 provided on the upper front portion of the sliding plate 56 for division by means of a pinion. Furthermore, on the sliding plate 56 for division, a spring bracket 125 necessary for interlocking with the sliding plate for raising and lowering PU described below is formed on the upper side, and a pin 126 is provided on one side.

FIG. 30 shows the shape of the dividing slide plate 56 capable of dividing the stocker 23 at an arbitrary position. Two sets of upper cam portions 120 and lower cam portions 121 are formed on the dividing slide plate 56 in the front-rear direction. The dividing protrusions 93 to 96 of the disc base 39 at the storage position where the dividing is performed rise along the slope of the upper cam portion 120 . Based on the disk base 39 to be divided, the lower side of the disk base controls the upper side of the division protrusions 93 to 96 by the lower side cam portion 121 . The division protrusions 93 to 96 that rise up on the slope along the upper cam portion 120 are separated by the separating portion 122 into the disk base 39 at the storage position and the disk base 39 above it. When the uppermost disc base 39 is selected, the division protrusions 106 to 109 of the top plate 104 are separated by the separation part 122 . The disc seat 39 on the lower side is further compressed by the pressing part 123 with the action of a spring. The front-back movement of the sliding plate 56 for dividing is realized by driving the rack 124 provided on the upper front of the sliding plate 56 for dividing by the pinion gears in the gear mechanisms 86 and 87 shown in FIG. 22 . Furthermore, a spring bracket 125 necessary for interlocking with the sliding plate for PU raising and lowering described below is formed on the upper side of the sliding plate 56 for division.

In FIG. 30, the relationship of the movement position of the division|segmentation protrusion 93,94 and the division|segmentation slide plate 96 is shown by reference code|symbol 93a1, 93a2,...94c4 etc. FIG. The 'a', 'b', and 'c' after the '93' and '94' representing the protrusions for division correspond to the disc base 39 above the selected disc base 39, the selected disc base 39, And the disc base 39 below the selected disc base 39. When the selected disc base 39 is the uppermost disc base 39 , the top plate 104 is above it. When the selected disc base 39 is the lowest disc base 39 , the bottom plate 101 is located below it.

Near the center of the front of the chassis 50, a pressing rod 140 for pressing the CD is provided, and when the stocker 23 is divided, it is pressed from the front to prevent the CD 24 stored in the lower disc holder 39 from exiting. The pressing lever 140 is rotated in conjunction with the dividing slide plate 56 to release the pressing state of the CD 24 in the divided state of the disc bottom 23 . The bevel gear 141 provided on the chassis 50 transmits the rotational driving force from the lift motor 52 through the gear mechanism 142 . A planetary gear mechanism is provided in the gear mechanism 142 so as to control transmission of the driving force to the bevel gear 141 in conjunction with the sliding plate 56 b for division. When the slide plate 56b for division is moved and the stocker 32 is divided, the conveyance path is cut off, and the drive force is prevented from being transmitted to the slide plate 54 for elevation.

On the front side of the chassis 50 is provided a lock mechanism 31 having a lock hole 143 for inserting a lock shaft 60 b protruding from the slide base 30 of the slide unit 60 . Furthermore, as shown in FIG. 31, the floating pin 60a set up on the slide base 30 is inserted into the stopper 130 installed on the stopper mounting hole 144 located at the width direction of the lock mechanism 31. outside. In addition, a coil spring 131 is arranged around the stopper 130, and the slide unit 60 is elastically supported by the chassis 50 in a floating state.

35A and 35B show the related structure of the PU lifting slide plate 137 which is connected with the sliding plate 56 for division and moves the slide base 30 of the pickup unit 25 up and down. FIG. 35 shows the sliding plate 137 itself for raising and lowering the PU; FIG. 35B shows the state of the chassis 50 with the sliding plate 137 for raising and lowering viewed from the left side.

As shown in FIG. 35A, a PU raising and lowering groove 151 for moving the slide base 30 up and down is formed on the PU raising and lowering slide plate 137. As shown in FIG. The slide plate 137 for raising and lowering the PU is guided by the pin 152 to move in the front-rear direction. The interlocking groove 153 is combined with the pin 126 of the sliding plate 56 for division, and when the sliding plate 56 for division is retreated beyond a certain degree, the interlocking retreat is carried out, and the rack 154 formed on the top and the pinion of the gear mechanism 86, 87 are carried out. Bite to allow further rearward movement. A spring bracket 155 for attaching a coil spring is also provided between the spring bracket 125 of the sliding plate 56 for division on the sliding plate 137 for PU raising and lowering.

As shown in FIG. 35B , the slide plate 137 for raising and lowering the PU is attached to the side plate 160 on the chassis 50 . The slide groove 161 is formed on the side plate 160 as a cam, and the pin 152 of the PU lifting slide plate 150 is combined to guide the movement of the PU lifting slide plate 150 in the front and rear direction, and is installed under the PU lifting slide plate 150. Lifting slide plate 54.

Furthermore, the slide plate 150 for PU elevation can also be integrally formed with the slide plate 56 for division|segmentation. In this case, the PU raising and lowering groove 151 is formed on the dividing slide plate 56 . If it is manufactured as a single body as in the embodiment, the length required in the front-rear direction can be shortened.

FIG. 36 shows the driving mechanism of the basic lifting slide plate 54 mounted on the chassis 50, and FIG. 37 shows the lifting slide plate 54 itself. The sliding plate 54 for raising and lowering is located in front of the chassis 50, and both sides are mechanically connected by a linkage rod 170, and move in opposite directions, and when one advances, the other retreats. The linkage rod 170 is capable of swinging and displacing around a central support shaft 171 . The slide plate 54 for elevating on the left side moves in the front-rear direction by the driving force transmitted from the elevating motor 52 to the pinion gear 172 via the bevel gear 141 .

As shown in FIG. 37 , stepped grooves 174 are formed in the sliding plate 54 for elevating, and are engaged with pins projecting horizontally from the bottom plate 101 of the stocker 23 . The step groove 174 acts as a cam to make the storage device 23 move up and down as a whole. The stocker 23 spatially aligns the divided disk base 39 to the height of the front end of the sliding plate 56 for division through the lifting displacement, so as to select the storage position for the division. In the present embodiment, the disk base 39 above the division position is selected, but a structure in which the bottom disk base 39 is selected is also possible.

38A and 38B show the structure of the gear mechanism 142 interposed between the lift motor 52 and the bevel gear 141 shown in FIG. 33 . FIG. 38A shows a state viewed from the left side; FIG. 38B shows a state viewed from the front. Driving force is transmitted from the worm gear 181 mounted on the output shaft of the lift motor 52 to the gear mechanism 142 . A planetary gear 182 is provided in the gear mechanism 142 to intermittently transmit driving force to the bevel gear 183 . When the pin 185 at the tip of the clutch lever 184 is pressed by the tip of the sliding plate 56b for division, the planetary gear 182 is displaced so that the meshed state with the bevel gear 183 is released. And, as long as the spring 186 does not press the pin 185 with the front end of the sliding plate 56b for division, it can maintain such a state that the driving force is transmitted from the planetary gear 182 to the bevel gear 183, and passes through the bevel gear 141 pair of Fig. 33 from the bevel gear 183. The lift slide plate 54 is driven.

The movement state of the division slide plate 56b in which the lift slide plate 54 stops being driven is equivalent to the reference symbols 93a4, 93b4, 93c4, 94a4, 94b4, 94c4 in FIG. The disk base 39 descends from the position of the turntable 38 . From this position, only the PU lift slide plate 130 is moved by the driving force from the split motor 54, and the pickup unit 25 is moved up and down.

39A and 39B show the lifting and lowering operation of the insertion and removal roller 35 in the insertion and removal mechanism 34 . Fig. 39A shows the rising state. The lift plate 190 is pulled upward by the spring, and at the same time, the switch stopper 89b is also pushed upward. Therefore, the switch pin 89a closes the insertion and removal opening 33 . On the lift plate 190 is formed a contact portion 191 that contacts and couples with the pin 61 a provided on the slide plate 61 shown in FIG. 18 . When the lifting plate 190 rises, the pin 193 of the lever 192 is pushed up, so that the insertion and removal roller 35 whose shaft is installed on the lever 192 rises.

Figure 39b shows that the pin 61a shown in Figure 18 is in contact with the contact portion 191 of the lifting plate 190, and the sliding base 30 is pulled down by the sliding plate 130 for lifting and lowering of the PU, and the pin 61a of the sliding unit 60 is also pulled down, and the connection is performed. Move, the lifting plate 160 is lowered. Since the lifting plate 190 does not push up the pin 193 of the lever 192, the insertion and removal roller 35 descends. Furthermore, since the switch stopper 89b descends, when the CD 24 is inserted, the switch pin 89a can escape, and the closed state of the insertion and removal port 33 is canceled.

Fig. 40 shows a cross section of the state shown in Fig. 39B. An insertion and extraction lever 195 is arranged near the inside of the insertion and extraction roller 35 and the support plate 36 . The insertion/extraction lever 195 displaces the switch slide plate 88a forward when the CD 24 is inserted as described below. When taking out a CD, the switch slide plate 88a is not displaced, and the take-out completion switch 90d of FIG. 22 is operated.

41A, 41B, 41C, 41D show the operation of the switch mechanism. Fig. 41A shows the state before CD24 is inserted. When the CD24 is inserted, the switch pin 89a is pushed to the left and right to generate a displacement, and the pin mounting plate 89d, which prevents the displacement of the pin slide plate 89c, moves, so the pin slide plate 89c is displaced under the action of the spring, and the insertion detection is performed. The switch 90a operates. When the CD 24 is reinserted, the insertion/extraction lever 195 is pushed, and the switch slide plate 88a moves forward. In this way, as shown in FIG. 41B , the insertion presence/absence switch 90b operates. The shutter member 88c is pressed and tilted from the front, but does not affect the insertion of the CD 24 .

Fig. 41C shows the state after the CD 24 is inserted into the device. Since the shutter sliding member 88b is tensioned by the spring 196, it moves rightward in the state where the switch sliding plate 88a is displaced forward. When the CD 24 is loaded inside and the shutter member 88c is no longer tilted, the shutter sliding member 88b is displaced to the right to lock the shutter member 88c. Furthermore, the insertion end switch 90c is also operated.

FIG. 41D shows a state in which the removal completion switch 90d is operated when the insertion/extraction lever 195 is taking out the CD 24 . If the CD 24 is left and the insertion/removal lever 195 is tilted, the insertion/removal completion switch 90d is pressed by the leaf spring 197 . When the extraction of the CD 24 is completed, the pressing state by the leaf spring 197 is released. The insertion/removal end switch 90d detects a change in the pressing force of the leaf spring 197 .

42A, 42B, 42C, and 42D show the shape and operation of the shutter member 88c. The shutter member 88c having the shape shown in FIG. 42A does not interfere with the insertion of the CD 24 as shown in FIGS. 42B to 42C. If the loaded CD 24 is conveyed in reverse as shown in FIG. 42D, the tilt is locked to prevent the movement of the CD 24. Furthermore, since the switch slide plate 88a is located at the position shown in FIG. 41A when taking out, the inclination of the shutter member 88c is not locked, and taking out is not prevented.

43A and 43B show the shape and movement of the insertion and removal rod 195 . As shown in FIG. 43B , the insertion/extraction lever 195 shown in FIG. 43A is inclined in different directions at the time of insertion 195 a and at the time of extraction 195 b. In this way, the sliding plate 88a for closing is displaced when inserted, but is not displaced when taken out.

44 and 45 show the structure of the locking mechanism 31 of FIG. 31 . FIG. 44 shows a tilted state, and FIG. 45 shows a flat state. The locking member 133 is biased by the spring 201 and is usually used in a state close to the right in the figure. The lock member 133 is provided with shaft lock holes 202 and 203 for inserting the lock shaft 606 of FIG. 31 , an interlocking guide groove 204 , a lock guide groove 205 , and a slide groove 206 . Pins 207 protruding outward are provided on both sides of the lifting base 138 .

46 and 47 show the shapes of the lifting base 138 and the locking member 133, respectively. Also formed on the locking member 136 is a locking member 210 that engages with the locking notch 132 serving as a joint portion of the locking piece 60C.

48A, 48B, and 48C show the shapes of the unlocking lever 139, the linkage lever 135, and the locking lever 134 shown in FIG. 44, respectively. As shown in FIG. 48A , the unlock lever 139 has a long hole 211 extending upward and downward, a pin 212 , a pressing portion 213 and the like. As shown in FIG. 48B, the interlocking rod 135 has a shaft hole 214, pins 215, 216, and the like. As shown in FIG. 48C, the lock lever 134 has a support shaft 217, a pin 218, a restricting portion 219, and the like.

FIG. 49 shows a state in which the lock mechanism 31 restricts the lock shaft 60b and the lock piece 60c, that is, the locked state. Displacement of the lock shaft 60 b in a plane parallel to the moving direction of the lock member 133 is restricted at the narrow diameter portions of the shaft lock holes 202 and 203 . Especially in the shaft locking hole 202, the locking rod 134 also limits the parallel displacement. In addition, the locking portion 210 is coupled to the locking notch 132 of the locking piece 60c to restrict displacement in the axial direction, that is, in the vertical direction.

FIG. 50 shows a state in which restriction by the lock mechanism 31 is released, that is, an unlocked state. When the slide plate 137 for raising and lowering the PU moves rearward, the unlocking lever 139 is interlocked, and when it is displaced rearward, the pressing part 213 presses the pin 215 of the interlocking lever 135 .
